    Hi,

    I’d like to correct a major mistake in your article: What you describe as free software is actually copyleft.

    You’re thinking of the GNU GPL, which requires that any derivative works of a covered work must be distributed under the GNU GPL as well. Free software also includes many non-copyleft licenses – the MIT license, the BSD license, and even the WTFPL license are all considered free, but are not as encouraged by the Free Software Foundation because they allow derivatives to be distributed as non-free software.

    Please rewrite this article as a comparison of copyleft and permissive licenses, or rewrite it to talk about the differences between the two movements that basically do the same work for different reasons.

    I told marktraceur about this article in #fsf. The article contains misinformation. Free software can, indeed, work with proprietary software. LibreOffice is a prime example of this. In contrast, Microsoft has dragged its feet in implementing Open Document Format for its word processor. And, let’s not forget that Apple’s proprietary system, OS X, is certified Unix built on free software. I hope this helps.
